Question

Simplify 2/7 - 5/6 + 3/4​

Answer 1

Step-by-step explanation:

LCM of 3,6,9=18

Now let us change each of the given fraction into an equivalent fraction having 18 as the denominator.

(2/3)x(6/6)=(12/18)

and (5/6)x(3/3)=(15/18)

and (1/9)x(2/2)=(2/18)

Now,

=(12/18)+(15/18)−(2/18)

=(12+15−2)/18

=(27−2)/18

=(25/18)

=[1(7/18)]

Answer 2

Answer:

$\frac{2}{7} - \frac{5}{6} + \frac{3}{4} \\ lcm \: of \: 7 - 6 - 4 = 84 \\ \frac{12 \times 2}{84} - \frac{14 \times 5}{84} + \frac{21 \times 3}{84}$
